Description

TECHNICAL FIELD

[0001] The present application relates to the field of water conservancy facilities, in particular to a water and sand separation system for irrigation waterway. BACKGROUND

[0002] The ditch is an important facility for water conservancy irrigation, and is usually used for the transition of irrigation water from the main river channel to the field. In this process, a large amount of silt and garbage will enter the ditch from the main river channel. Since the ditch is obviously narrower than the river channel, a large amount of silt and garbage will easily cause blockage. Therefore, it needs to be cleaned regularly. The current common processing scheme is to block it with a filter screen and then remove it with a special tool such as a excavator. For example, the patent document with the publication number CN115852904A discloses an environmental protection ditch blocking device. However, this scheme has some problems. Because the silt and garbage cleaning can only be performed at intervals, when the ditch is not blocked, the garbage will flow along the ditch to the field, causing pollution of the field. And once the ditch is blocked, if it cannot be cleaned in time, it will affect agricultural irrigation. And as long as there is any blockage in the ditch, the ditch will not be able to irrigate normally, and the fault tolerance is too low. SUMMARY

[0003] To solve the above technical problems, the present application provides a water and sand separation system for irrigation waterway, which can effectively guide the silt and garbage to the bypass ditch, avoid blockage caused by accumulation in the main ditch, and make the cleaning process more convenient.

[0004] The technical scheme adopted by the present application to solve the technical problems is: a water and sand separation system for irrigation waterway, comprising a main ditch and a bypass ditch.

[0005] The upstream port of the bypass ditch is connected to the upstream bypass port of the main ditch.

[0006] The downstream port of the bypass ditch is connected to the downstream bypass port of the main ditch.

[0007] The main ditch is provided with a separation section upward from the upstream bypass port, and the ditch bottom of the bypass ditch and the ditch bottom of the separation section are both provided with a silt sedimentation tank with a deeper depth, and the silt sedimentation tank of the bypass ditch and the silt sedimentation tank of the separation section are mutually butted.

[0008] A first fence is arranged in the main ditch, a first end of the first fence is butted to the downstream side of the upstream bypass port, a second end of the first fence is butted to the side of the main ditch away from the upstream bypass port, and a second fence is arranged at the downstream bypass port.

[0009] The bypass ditch is arranged to guide the garbage and silt to the bypass ditch, and the garbage and silt can be cleaned to avoid the garbage and silt from being accumulated in the main ditch.

[0010] Specifically, first, due to the arrangement of the separation section, the silt sinking characteristics, the silt will be deposited in the silt deposition tank of the separation section, and due to the deeper depth and the butt joint with the bypass ditch, the silt in the silt deposition tank will move to the silt deposition tank of the bypass ditch under the impact of the water flow, and due to the shallower depth of the ditch bottom of the main ditch except the separation section, the silt will be difficult to flow out of the silt deposition tank, and therefore, the cleaning of the silt can be performed in the bypass ditch.

[0011] And for the garbage with a larger volume, due to the existence of the first fence, the garbage in the main ditch will be blocked and guided to the bypass ditch, and the garbage will flow to the bypass ditch, and due to the second fence, the garbage in the bypass ditch will be blocked and stopped, and the garbage in the bypass ditch can be cleaned regularly.

[0012] No matter the silt or the garbage with a larger volume, they can be guided to the bypass ditch to avoid being accumulated and blocked in the main ditch, and the garbage cleaning operation can be performed in the bypass ditch, so that the water flow in the main ditch will not be affected. The silt and the garbage with a larger volume can be separated very conveniently, and the water flow in the ditch will not be affected.

[0013] Preferably, the middle section slot of the silt deposition tank is provided with a partition plate, and the partition plate extends to the separation section and the bypass ditch in the upstream and downstream respectively.

[0014] The middle section slot of the silt deposition tank is not provided with a partition plate, the silt first enters the separation section, flows into the silt deposition tank, and then flows into the silt deposition tank corresponding to the partition plate in the downstream of the water flow. The silt cannot flow out of the silt deposition tank in the upstream, so that the silt can flow more clearly to the bypass ditch.

[0015] Preferably, the partition plate is detachably matched with the slot of the silt deposition tank, so as to flexibly adjust the specific position of the partition plate distribution, and change the size of the upstream and downstream openings of the silt deposition tank.

[0016] Preferably, the downstream section of the partition plate is provided with a plurality of discharge holes, so that the upstream of the partition plate is completely isolated, and the silt above the downstream can be appropriately deposited downward.

[0017] Preferably, the second end of the first fence is inclined upward in the upstream, so that the garbage can more easily flow to the bypass ditch.

[0018] Preferably, the bottom of the bypass ditch without the isolation plate is provided with a garbage collection frame. The garbage collection frame is used for collecting garbage and silt. After being filled, the garbage and silt are directly lifted up and taken out for cleaning.

[0019] Preferably, the upper side wall of the garbage collection frame is a filter plate, and the bottom of the garbage collection frame is a closed container. The filter plate arranged on the upper part can block the silt, and the closed lower part can prevent the silt from flowing out.

[0020] Preferably, the garbage collection frame is open on the side corresponding to the upstream. This facilitates the entry of silt and garbage into the garbage collection frame.

[0021] Preferably, the first end of the first fence is hingedly arranged on the downstream side of the upstream bypass opening, and the second end of the first fence is detachably connected to the side of the main road ditch away from the upstream bypass opening. In this way, the first fence can be opened.

[0022] Preferably, the second fence comprises a lower closed plate and an upper filter screen plate. In this way, the lower part blocks the silt, and the upper part intercepts the garbage.

[0023] Advantages of the present application:

[0024] The present application can effectively guide the silt and garbage in the bypass ditch, avoid the accumulation of silt and garbage in the main road ditch, and facilitate the cleaning of silt and garbage in the bypass ditch. BRIEF DESCRIPTION OF DRAWINGS

[0031] In order to deepen the understanding of the present application, the present application will be further described in detail below in conjunction with the drawings and examples, which are only used to explain the present application and do not constitute a limitation on the scope of protection of the present application.

[0032] EMBODIMENT

[0033] As Figure 1 shown, a water and sand separation system for irrigation channel, including main road ditch 1 and bypass ditch 2, the upstream port of the bypass ditch 2 is connected to the upstream bypass port of the main road ditch 1, the downstream port of the bypass ditch 2 is connected to the downstream bypass port of the main road ditch 1.

[0034] The main road ditch 1 is provided with a separation section from the upstream bypass port, the ditch bottom of the bypass ditch 2 and the ditch bottom of the separation section are both provided with a sediment settling tank 5 with a deeper depth, the sediment settling tank 5 of the bypass ditch 2 and the sediment settling tank 5 of the separation section are mutually butted, the first fence 3 is arranged in the main road ditch 1, the first end of the first fence 3 is butted to the downstream side of the upstream bypass port, the second end of the first fence 3 is butted to the side of the main road ditch 1 away from the upstream bypass port, and the second fence 4 is arranged at the downstream bypass port.

[0035] The present scheme is provided with a bypass ditch 2 for guiding garbage and sediment to this place for centralized cleaning, avoiding the accumulation of garbage and sediment in the main road ditch 1.

[0036] Specifically, first, due to the arrangement of the separation section, the characteristics of sediment sinking, sediment will be deposited and concentrated in the sediment settling tank 5 of the separation section, and due to its deeper depth and butt joint with the bypass ditch 2, the sediment in the sediment settling tank 5 will move to the sediment settling tank 5 of the bypass ditch under the impact of water flow, and due to the shallower depth of the ditch bottom of the main road ditch 1 except the separation section, the sediment will be difficult to flow out of the sediment settling tank 5, so the cleaning of sediment can be carried out in the bypass ditch 2.

[0037] As for the garbage with larger volume, due to the existence of the first fence 3, the garbage in the main road ditch 1 will be blocked and guided to the bypass ditch 2, and the garbage will flow to the bypass ditch 2, and due to the second fence 4, the garbage in the bypass ditch 2 will be blocked and stay, and the garbage in the bypass ditch 2 can be cleaned regularly.

[0038] The above-mentioned silt and bulky garbage can be drained to the bypass channel 2, avoiding accumulation and blockage in the main channel 1. The operation of cleaning garbage can be carried out in the bypass channel 2, so as not to affect the flow of the main channel 1. The whole process can separate silt and bulky garbage very conveniently, and will not affect the flow of the channel.

[0039] The middle section of the silt settling tank 5 is provided with a partition plate 6, which extends to the separation section and the bypass channel 2 respectively. The middle section of the silt settling tank 5 is not provided with a partition plate 6, and the silt first enters the separation section and then flows into the silt settling tank 5. The silt cannot flow out of the silt settling tank 5, so that the silt flows more clearly into the bypass channel 2. That is, the upstream section and the downstream section of the silt settling tank 5 are both provided with an open slot, so that the silt and garbage enter from the upstream open slot of the silt settling tank 5 and then flow out from the downstream open slot.

[0040] The second end of the first fence 3 is inclined upward to the upstream. This can make the garbage flow more easily to the bypass channel 2.

[0041] The partition plate 6 can be detachably fitted to the slot of the silt settling tank 5. In order to flexibly adjust the specific position of the partition plate 6, the size of the upstream and downstream openings of the silt settling tank 5 can be changed.

[0042] The downstream section of the partition plate 6 is provided with a plurality of discharge holes. The upstream of the partition plate 6 is completely isolated, and the downstream can appropriately deposit the silt above.

[0043] The bottom of the bypass channel 2 without the partition plate 6 is provided with a garbage collection frame 7. The garbage collection frame 7 is used to collect garbage and silt. When it is full, the garbage and silt can be directly lifted out for cleaning.

[0044] The upper side wall of the garbage collection frame 7 is a filter plate 10, and the bottom of the garbage collection frame 7 is a closed container 11. The filter plate 10 arranged in the upper part can block the silt, and the closed lower part can prevent the silt from flowing out.

[0045] The garbage collection frame 7 is open on one side corresponding to the upstream. This is convenient for the silt and garbage to enter the garbage collection frame 7.

[0046] The first end of the first fence 3 is hingedly connected to the downstream side of the upstream bypass opening, and the second end of the first fence 3 is detachably connected to the side of the main channel 1 away from the upstream bypass opening. In order to open the first fence 3. When the water in the channel is relatively clear, the first fence 3 can be swung open, and the second end of the first fence 3 is fixed to the upstream side of the upstream bypass opening.

[0047] The second fence 4 comprises a lower closing plate 9 and an upper filter screen plate 8, so that the lower part blocks the silt and the upper part intercepts the garbage.

[0048] The beneficial effects of the present application are:

[0049] The present application can effectively guide the silt and garbage in the bypass ditch 2, avoid the blockage caused by the accumulation in the main road ditch 1, and clean the silt and garbage in the bypass ditch 2, so that the whole process is more convenient.

In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0051] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as the limitation of the patent scope of the present application. It should be pointed out that, for those skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which all belong to the protection scope of the present application.
